Abstract: 1510659 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONISIEMENS SpA 23 May 1975 [17 June 1974] 22690/75 Heading H4K [Also in Division G4] A "page" of data held in a data bank is displayed on a T.V. set or monitor screen via a telephone system by dialling the address of a desired data bank, the engaged tone confirming connection, pressing a control button to connect the telephone line to an adapter circuit connected to the T.V. set or monitor, dialling the address of a "page" in the data bank, the address being stored and displayed, pressing the control button again to send the address to the data bank and display the "page" sent back in response on the screen. The control button switches off one of a pair of LEDs (D 1 , D 2 ) optically coupled to transistors (T 1 , T 2 ) to connect the dialling output to a coder (UC) and switch flipflops (FF 1 , FF 2 ) to connect the telephone line to the adapter circuit. The dialling page address, between start and stop bits, is assembled in a buffer MB for display (see later, for display of page). When the control button is pressed the address is serialized by a converter SP and transmitted via modem MD to the data bank. Data from the bank enters via modem MD, and each character is staticized by converter SP, buffered by MB and assembled into a page in register MQ. Each line is recirculated 10 times through a line register MR, switch CO and page register MQ while character generators GC generate a corresponding line of the display in which each character is a 7 Î 5 matrix, there being 3 blank sweeps between lines. The output of GC is serialized at PS fed via V.H.F. modulator MO to the aerial input of the T.V. set.

[Also in Division F2] An electromagnetically operated valve, adapted for preventing unauthorized use of an I.C. engine by interrupting the fuel supply thereto, comprises a tube 42, formed with at least one longitudinal recess 44 and a member slidably mounted within the tube and formed with a section 46, which is a close sliding fit, and narrowed sections 47 and 51. The length of section 46 is less than that of the recesses 44, so that when the member is moved to the left from the valve-closed position shown, fuel can flow through the recesses past section 46 and continue down the tube past sections 47 and 51. In the closed position shown, section 51 co-operates with a cork seat 52. A spring-loaded bell 48, mounted in section 46, prevents movements of the member unless in response to either of solenoids 49 and 50, which are respectively for closing and opening the valve. The valve is adapted to be mounted in the fuel line of a motor vehicle between the fuel tank and the engine. An electrical circuit, Fig. 3 (not shown), includes a switch for energizing one or other solenoid. The circuit for energizing solenoid 50 includes a fuse, which may be blown by depressing a push-button.

Title: Electrical switches
IPC: H01H33/32
Filed: 1970-05-13
Abstract: 1,246,434. Fluid pressure operated switches. SIEMENS A.G. 13 May, 1970 [13 May, 1969], No. 23089/70. Heading H1N. An electric switch, especially a high voltage switch, is operated by means of fluid under pressure, controlled by a valve 17, acting on one or both faces of a differential piston 10 and causing a movable contact rod to assume one of its two positions, an insulating rod 22 actuating the valve. A motor 41 and a compressor 40 maintain the fluid in the reservoir 36 and the line 35 at a high pressure. Changeover valve 30, which may be electromagnetically operated, connects the lower face of the piston 27 with the line 35 causing insulating rod 22 to move valve 17 into the position shown. In this position, smaller piston face 10 is at high pressure, whereas large face 11 is connected to low pressure insulator chamber 26. The contact rod 3 is thus moved down, opening the contacts (not shown) in the switching chamber 2. For the closing operation, rod 22 is lowered by disconnecting line 29 from the high pressure line 35 by means of the valve 30. The valve 17 now closes plate 21 against seat 25, exposing both piston faces 10, 11 to the high pressure fluid, e.g. oil. The lower face 11 being larger, due to the area of rod 3, causes rod 3 to rise, closing the contacts. The column insulator 12 is secured to the earthed metal truck 14, on which are also mounted some of the switch control parts.

Title: Hydraulically actuated crutch
IPC: A47B53/02
Filed: 1964-06-04
Abstract: 1,006,965. Crutch. FAR-PRIT ASSOCIATE Inc. June 4, 1964 [June 4, 1963], No. 23100/64. Heading A5R. A variable length crutch comprises a pair of telescopic sections and an electrically operated hydraulic power system carried by the crutch for lengthening or shortening the crutch so that a person may raise or lower himself. The crutch comprises cylinder 12 with arm pit rest 16 acting as reservoir for hydraulic fluid, piston rod 14 with piston 20 slidable in cylinder 12 and holding means in which is situated an electrically driven motor and pump unit 35 and reverse flow control means 36 e.g. a check valve, connected to reservoir 16 by conduit 44, and to cylinder 12 by conduit 46, the unit 35 and value 36 being controlled by finger tip controls 38 and 40 respectively. Actuation of the pump causes hydraulic fluid to pass into cylinder 12, forcing the piston 20 downwards and once a certain negative pressure, greater than that caused by gravity on the piston 20, is obtained on the pump side of the valve 36, valve 36 opens to allow fluid to pass from reservoir 16 to the pump, so that the piston can be forced down to lengthen the crutch to the required extent. To shorten the crutch, the motor and pump are switched off and valve 36 is opened by control means 40 to allow fluid to pass from cylinder 12 to reservoir 16. Alternatively, the pump may be operated to pump fluid from cylinder 12 to the reservoir 16. A vent 26 prevents accumulation of positive or negative pressures below piston 20. The arm pit rest 16 may be cushioned and the piston rod 14 may be provided with resilient ferrule 28. The crutch may be made of metal.

Apparatus for compreasing refuse in three directions at right angles comprises a filling chamber 1 connectible to a refuse delivery shoot D, a first compacting plate 5 oscillatable about a horizontal axis 6 between a lowered position in which it forms a shoot from the filling chamber 1 to the compression chamber 2 and a raised position in which it closes the chamber 2, a second compacting plate 10 reciprocable vertically and a third compacting plate 13 reciprocable horizontally to effect final compression of the refuse against a stop 17. The stop 17 can be withdrawn to allow the plate 13 to eject the compressed refuse through an elbow 20 into a bin 21. A curved plate 8 carried by the plate 5 forms a closure for the filling chamber 1 when the plate 5 is in its raised position. Hydraulic piston-cylinder units 9, 12, 14, 18 operate the plates 5, 10, 13 and stop 17 respectively, and all may be controlled by switch means operated when refuse interrupts a light beam 22.
